spirit of randomness

There is this certain episode of Mr Bean.
He was trying to go down the staircase
But there is an elderly lady in front of him
Walking really slowly and the staircase is too narrow for him to pass
So Bean tried all ways and means to get pass
And in the end climb off the railing to overtake her.

Only to find yet another elderly man in front of him.

I understand how Bean felt just now when I went to buy dinner.
